H4 — Beta vulgaris subsp. vulgaris

Summary

BvH4 (BVRB_7G174280) on sugar beet chromosome 7 encodes a histone H4 protein with a histone-fold domain and CENP-T/H4_C region, exhibiting structural constituent of chromatin, DNA binding, histone binding, calmodulin binding, calcium ion binding, protein serine/threonine kinase activity, and multiple chromatin-modifying activities including histone acetylase, deacetylase, and methylase functions. The gene is associated with nucleosome assembly, epigenetic regulation of gene expression, photoperiodism and flowering, regulation of vegetative-to-reproductive phase transition, vernalization response, seed maturation, secondary shoot formation, and responses to UV-B, hydrogen peroxide, and mechanical stimuli. It is linked to bacterial blight disease resistance, flowering time, leaf and root morphology, seed development, chloroplast development, brassinosteroid and abscisic acid sensitivity, jasmonic acid content, stomatal closure, and stress responses including salt tolerance. Related genes in other species are linked to circadian rhythm, disease resistance, and salt stress response.
